MOV → MP4.
Usually instantly.

Here's what converter sites don't tell you: an iPhone .mov and an .mp4 usually contain the same video in a different wrapper. We swap the wrapper on your device — no re-encoding, no quality loss, near-instant — and only re-encode if your player truly needs H.264.

Why iPhone videos won't play on your PC

iPhones record H.264 or HEVC video inside a QuickTime .mov container. Windows apps, PowerPoint, and many players expect .mp4. When the video inside is H.264, the fix is a pure container swap — same pixels, new envelope, done in seconds even for big files because nothing uploads. Newer iPhones record HEVC (H.265), which some PCs can't decode at all — that's what the Force H.264 mode is for: a real re-encode into the codec everything on earth plays.

FAQ

Is there a file size limit?

No hard cap — your device's memory is the limit. Multi-GB files work best on a computer in Chrome.

Which mode for PowerPoint's "codec unavailable" error?

Try instant rewrap first; if PowerPoint still complains, the video is HEVC — run it again with Force H.264.

Is my video uploaded?

Never. The rewrap runs in your browser using your own hardware. A 2 GB video would take ages to upload anywhere — skipping the upload IS the speed trick.
